Electronic Logbook platform for NICA experiments

Abstract

The acquisition of experimental data is an integral part of all modern high-energy physics experiments. This task is of particular importance in the experiments of the NICA project, which is currently under construction at the Joint Institute for Nuclear Research, due to the high interaction rate of heavy ion collision events and the complexity of detector systems. During experiments sessions, not only the collected experimental data are important, but also parameters and conditions under which the experiments are conducted. To record and store all the information, the shift crew needs a structured and systematized online electronic journal. The article presents a new implementation of the Online Logbook System designed to automate the latter process for the NICA experiments. The Logbook System allows collaboration members to record information during experiment runs on current events, operation conditions of the detectors and their parameters, which are further used in raw data processing, reconstruction and physics analysis of the particle collision events in the experiments. A new version of the Electronic Logbook has been implemented as a configurable platform to be used in different experiments on particle collisions, such as a fixed target BM@N and collider MPD and SPD experiments of the NICA project. In addition, the specialized API and user Web service developed for viewing, changing and searching for the required logbook data, as well as a set of auxiliary services and a common deployment system are considered.
